I made a list of all the astronomy programs I need/use, and it comes to about 40!!! Wow, that's a lot.
However i've prioritised them into programs I need JUST for Friday night, and that comes to about 10, including Windows XP, Canon Driver Software, Images Plus (camera capture), Raw Shooter Premium, Starry Night, PHD Guiding, IC-Capture.AS, AlsICCA, and Photoshop.
That'll get me going
The format is happening about 9:30am Friday so will give me a few hours (in-between goodbye lunches and afternoon teas) to install some stuff
